DETAILED DESCRIPTION

As discussed above, AR systems provide users within graphical userinterfaces (GUI) to display a live direct or indirect view of aphysical, real-world environment, wherein elements of the view areaugmented by computer-generated sensory inputs. For example, an ARinterface may present media content at positions within a display of aview of a real-world environment, such that the media content appears tointeract with elements in the real-world environment. Certain exampleembodiments discussed herein therefore provide an AR system to generateand present a “shared” AR experience, wherein multiple users may takepart in the same AR session in real-time.

Accordingly, a shared AR system is disclosed which performs operationsthat include: accessing image data at a client device, the image datacomprising a set of image features, the set of image features defining asurface of an object; determining a position of a user of the clientdevice based on the set of image features; causing display of aprojection that extends from the position of the user upon apresentation of the image data at the client device, the projectioncomprising a graphical property and having a trajectory based on theposition of the user of the client device; detecting an intersection ofthe projection and the surface of the object based on the trajectory,the intersection corresponding with a portion of the surface of theobject; generating a request that includes an identification of theportion of the surface of the object at the client device; andpresenting the portion of the surface of the object based on thegraphical property of the projection at the client device in response tothe request that includes the identification of the portion of thesurface of the object.

In some embodiments, the display of the projection may be responsive toa user input received at the client device. For example, a user of theclient device may provide a tactile input at the client device, whereinthe tactile input comprises a selection of a graphical icon, or a pointwithin the presentation of the image data at the client device.Responsive to receiving the input, the shared AR system may present aprojectile that extends from a position of the user within thepresentation of the image data at the client device. As an illustrativeexample, the projectile may be presented as a stream of paint extendingfrom a location within the presentation of the image data at the clientdevice, such that the user of the client device may change a trajectoryof the projectile by moving and re-orienting the client device. A usermay therefore “paint” objects detected in a presentation of image dataat the client device by pointing the projectile (i.e., paint stream)presented at the client device at the objects. In some embodiments, onlysome portions and specific areas of an area (i.e., a surface of abuilding) may be augmented with AR paint.

In some embodiments, the objects may include other virtual (i.e., AR)objects presented within the presentation of the image data at theclient device. For example, in such embodiments, the shared AR systemmay detect AR content displayed within the presentation of the imagedata based on location data from the client device, and location dataassociated with the AR content. The user may thereby paint the ARcontent displayed within the presentation of the image data by pointingthe projectile extending from the client device to the object.

In some embodiments, the shared AR system may assign a user of theclient device to a “team” responsive to detecting the client deviceassociated with the user at a location. Detection of the client deviceat a location may be based on a geo-fence that encompasses the location,location data extracted from the client device, or based on thedetection of landmarks associated with the location within image datacaptured or displayed at the client device. The team may correspond witha graphical property, such as a color or pattern (or color and pattern),wherein the projection (i.e., paint) may be presented at the clientdevice based on the corresponding graphical property.

In some embodiments, a user of the shared AR system may provide an inputthat selects a team or graphical property (i.e., paint color, paintpattern). For example, responsive to detecting the client device at alocation (i.e., the client device transgresses a boundary of ageo-fence), the shared AR system may cause display of a menu elementthat includes a display of one or more graphical properties from whichthe user may select, or a display of one or more teams from which theuser may select. The user may then provide an input that selects a teamor graphical property from the menu element, and in response the sharedAR system may assign the graphical property (or team) to a user profileassociated with the user.

In some embodiments, the user may paint an object depicted in image datawithin a presentation of the image data at a client device by directingthe display of the projectile extending from the client device at theobject, wherein the object has a corresponding total area based on asurface of the object. The shared AR system may determine a ratio of anarea of a portion of the object painted by the user to the total area ofthe surface of the object in order to calculate a score to be presentedto the user at the client device. For example, as the user paints theobject, an indication of a coverage of the object by the user may bedisplayed at the client device of the user. The indication may bepresented as a numerical value (i.e., 25, 25%), or as a graphicalindicator that presents the value based on a visual indication (i.e., abar).

In some embodiments, objects painted by the user in the presentation ofthe image data at the client device of the user may be tagged to thelocation, such that other users may be able to see what the user haspainted. For example, a first user may paint a building at a locationwithin a presentation of image data at a first client device, such thatthe building appears to be covered in a first color of paint. A seconduser may then see the building being painted in real-time through asecond client device.

In some embodiments, a user of the shared AR system may provide an inputthat selects an “eraser” function, and wherein selection of the eraserfunction enables the user to remove “paint” applied to a surface withinthe presentation of the image data at a client device. In suchembodiments, the user may erase the AR content presented along surfacesof objects within an AR environment by “painting” the surfaces with aneraser projectile that extends from a position of the user at the clientdevice. Accordingly, a user may “erase” paint applied by another user.

Certain embodiments of the shared AR system may include a game, whereinplayers of the game (i.e., users of the shared AR system) are incentedto “paint” as much of a location with their corresponding paint color(i.e., graphical property that corresponds with their team). The gamemay be “won” by the user, or team of users, that paint the largestpercentage of the objects in a location over a predefined period of time(i.e., 5 minutes), or based on which user, or team of users, completespainting all objects (or a set of objects) before the other user or teamof users. Progress may be presented at the client devices thatcorrespond with the players of the game, wherein the progress may beindicated as a score.

Users may be recruited onto teams based on proximity to a geographiclocation, as well as user attributes of the users. For example, upondetecting a client device of a user at a location, the shared AR systemmay designate the user to a team from among a plurality of teams,wherein each team has a corresponding identifier, such as a color (i.e.,a graphical property). The user may then paint objects within apresentation of image data at their client device with the identifier(i.e., color) associated with their corresponding team.

In some embodiments, a game executed by the shared AR system may notifyplayers of specific objects to find and “paint.” The specific objectsmay include landmarks including but not limited to buildings, signs, andstatues. For example, responsive to detecting the client device at alocation, the shared AR system may identify one or more objects based onthe location. For example, the share AR system may maintain a repositorythat includes a listing of objects at a given location.

The shared AR system may then notify the players of the objects to beidentified and painted. Users of the shared AR system may then be givena period of time in which to paint as many of the objects as they canbefore the period of time expires. Progress may be visible to the usersas a shared AR experience.

FIG. 1 is a block diagram showing an example messaging system 100 forexchanging data (e.g., messages and associated content) over a network.The messaging system 100 includes one or more client device 102 whichhost a number of applications including a messaging client application104. Each messaging client application 104 is communicatively coupled toother instances of the messaging client application 104 and a messagingserver system 108 via a network 106 (e.g., the Internet).

Accordingly, each messaging client application 104 is able tocommunicate and exchange data with another messaging client application104 and with the messaging server system 108 via the network 106. Thedata exchanged between messaging client applications 104, and between amessaging client application 104 and the messaging server system 108,includes functions (e.g., commands to invoke functions) as well aspayload data (e.g., text, audio, video or other multimedia data).

The messaging server system 108 provides server-side functionality viathe network 106 to a particular messaging client application 104. Whilecertain functions of the messaging system 100 are described herein asbeing performed by either a messaging client application 104 or by themessaging server system 108, it will be appreciated that the location ofcertain functionality either within the messaging client application 104or the messaging server system 108 is a design choice. For example, itmay be technically preferable to initially deploy certain technology andfunctionality within the messaging server system 108, but to latermigrate this technology and functionality to the messaging clientapplication 104 where a client device 102 has a sufficient processingcapacity.

The messaging server system 108 supports various services and operationsthat are provided to the messaging client application 104. Suchoperations include transmitting data to, receiving data from, andprocessing data generated by the messaging client application 104. Insome embodiments, this data includes, message content, client deviceinformation, geolocation information, media annotation and overlays,message content persistence conditions, social network information, andlive event information, as examples. In other embodiments, other data isused. Data exchanges within the messaging system 100 are invoked andcontrolled through functions available via GUIs of the messaging clientapplication 104.

Turning now specifically to the messaging server system 108, anApplication Program Interface (API) server 110 is coupled to, andprovides a programmatic interface to, an application server 112. Theapplication server 112 is communicatively coupled to a database server118, which facilitates access to a database 120 in which is stored dataassociated with messages processed by the application server 112.

Dealing specifically with the Application Program Interface (API) server110, this server receives and transmits message data (e.g., commands andmessage payloads) between the client device 102 and the applicationserver 112. Specifically, the Application Program Interface (API) server110 provides a set of interfaces (e.g., routines and protocols) that canbe called or queried by the messaging client application 104 in order toinvoke functionality of the application server 112. The ApplicationProgram Interface (API) server 110 exposes various functions supportedby the application server 112, including account registration, loginfunctionality, the sending of messages, via the application server 112,from a particular messaging client application 104 to another messagingclient application 104, the sending of media files (e.g., images orvideo) from a messaging client application 104 to the messaging serverapplication 114, and for possible access by another messaging clientapplication 104, the setting of a collection of media data (e.g.,story), the retrieval of a list of friends of a user of a client device102, the retrieval of such collections, the retrieval of messages andcontent, the adding and deletion of friends to a social graph, thelocation of friends within a social graph, opening and application event(e.g., relating to the messaging client application 104).

The application server 112 hosts a number of applications andsubsystems, including a messaging server application 114, an imageprocessing system 116, a social network system 122, and a shared ARsystem 124. The shared AR system 124 is configured to generate andpresent AR content at the client device 110. Further details of theshared AR system 124 can be found in FIG. 3 below.

The messaging server application 114 implements a number of messageprocessing technologies and functions, particularly related to theaggregation and other processing of content (e.g., textual andmultimedia content) included in messages received from multipleinstances of the messaging client application 104. As will be describedin further detail, the text and media content from multiple sources maybe aggregated into collections of content (e.g., called stories orgalleries). These collections are then made available, by the messagingserver application 114, to the messaging client application 104. Otherprocessor and memory intensive processing of data may also be performedserver-side by the messaging server application 114, in view of thehardware requirements for such processing.

The application server 112 also includes an image processing system 116that is dedicated to performing various image processing operations,typically with respect to images or video received within the payload ofa message at the messaging server application 114.

The social network system 122 supports various social networkingfunctions services, and makes these functions and services available tothe messaging server application 114. To this end, the social networksystem 122 maintains and accesses an entity graph 304 within thedatabase 120. Examples of functions and services supported by the socialnetwork system 122 include the identification of other users of themessaging system 100 with which a particular user has relationships oris “following,” and also the identification of other entities andinterests of a particular user.

The application server 112 is communicatively coupled to a databaseserver 118, which facilitates access to a database 120 in which isstored data associated with messages processed by the messaging serverapplication 114.

FIG. 2 is block diagram illustrating further details regarding themessaging system 100, according to example embodiments. Specifically,the messaging system 100 is shown to comprise the messaging clientapplication 104 and the application server 112, which in turn embody anumber of some subsystems, namely an ephemeral timer system 202, acollection management system 204 and an annotation system 206.

The ephemeral timer system 202 is responsible for enforcing thetemporary access to content permitted by the messaging clientapplication 104 and the messaging server application 114. To this end,the ephemeral timer system 202 incorporates a number of timers that,based on duration and display parameters associated with a message,collection of messages (e.g., a story), or graphical element,selectively display and enable access to messages and associated contentvia the messaging client application 104. Further details regarding theoperation of the ephemeral timer system 202 are provided below.

The collection management system 204 is responsible for managingcollections of media (e.g., collections of text, image video and audiodata). In some examples, a collection of content (e.g., messages,including images, video, text and audio) may be organized into an “eventgallery” or an “event story.” Such a collection may be made availablefor a specified time period, such as the duration of an event to whichthe content relates. For example, content relating to a music concertmay be made available as a “story” for the duration of that musicconcert. The collection management system 204 may also be responsiblefor publishing an icon that provides notification of the existence of aparticular collection to the user interface of the messaging clientapplication 104.

The collection management system 204 furthermore includes a curationinterface 208 that allows a collection manager to manage and curate aparticular collection of content. For example, the curation interface208 enables an event organizer to curate a collection of contentrelating to a specific event (e.g., delete inappropriate content orredundant messages). Additionally, the collection management system 204employs machine vision (or image recognition technology) and contentrules to automatically curate a content collection. In certainembodiments, compensation may be paid to a user for inclusion of usergenerated content into a collection. In such cases, the curationinterface 208 operates to automatically make payments to such users forthe use of their content.

The annotation system 206 provides various functions that enable a userto annotate or otherwise modify or edit media content associated with amessage. For example, the annotation system 206 provides functionsrelated to the generation and publishing of media overlays for messagesprocessed by the messaging system 100. The annotation system 206operatively supplies a media overlay (e.g., a filter, lens) to themessaging client application 104 based on a geolocation of the clientdevice 102. In another example, the annotation system 206 operativelysupplies a media overlay to the messaging client application 104 basedon other information, such as, social network information of the user ofthe client device 102. A media overlay may include audio and visualcontent and visual effects. Examples of audio and visual content includepictures, texts, logos, animations, and sound effects, as well asanimated facial models. An example of a visual effect includes coloroverlaying. The audio and visual content or the visual effects can beapplied to a media content item (e.g., a photo or video) at the clientdevice 102. For example, the media overlay including text that can beoverlaid on top of a photograph generated taken by the client device102. In another example, the media overlay includes an identification ofa location overlay (e.g., Venice beach), a name of a live event, or aname of a merchant overlay (e.g., Beach Coffee House). In anotherexample, the annotation system 206 uses the geolocation of the clientdevice 102 to identify a media overlay that includes the name of amerchant at the geolocation of the client device 102. The media overlaymay include other indicia associated with the merchant. The mediaoverlays may be stored in the database 120 and accessed through thedatabase server 118.

In one example embodiment, the annotation system 206 provides auser-based publication platform that enables users to select ageolocation on a map, and upload content associated with the selectedgeolocation. The user may also specify circumstances under which aparticular media overlay should be offered to other users. Theannotation system 206 generates a media overlay that includes theuploaded content and associates the uploaded content with the selectedgeolocation.

In another example embodiment, the annotation system 206 provides amerchant-based publication platform that enables merchants to select aparticular media overlay associated with a geolocation via a biddingprocess. For example, the annotation system 206 associates the mediaoverlay of a highest bidding merchant with a corresponding geolocationfor a predefined amount of time

FIG. 3 is a block diagram illustrating components of the shared ARsystem 124 that configure the shared AR system 124 to perform operationsto generate and cause display of a notification based on aclassification associated with a user connection, according to certainexample embodiments.

The shared AR system 124 is shown as including a user profile module302, a notification module 304, and a presentation module 306, allconfigured to communicate with each other (e.g., via a bus, sharedmemory, or a switch). Any one or more of these modules may beimplemented using one or more processors 308 (e.g., by configuring suchone or more processors to perform functions described for that module)and hence may include one or more of the processors 308. In certainembodiments, the avatar notification system 124 may include or haveaccess to the database 120, wherein the database 120 may comprise acollection of media content indexed based on user attributes andastrological signs.

Any one or more of the modules described may be implemented usinghardware alone (e.g., one or more of the processors 308 of a machine) ora combination of hardware and software. For example, any moduledescribed of the avatar notification system 124 may physically includean arrangement of one or more of the processors 308 (e.g., a subset ofor among the one or more processors of the machine) configured toperform the operations described herein for that module. As anotherexample, any module of the avatar notification system 124 may includesoftware, hardware, or both, that configure an arrangement of one ormore processors 308 (e.g., among the one or more processors of themachine) to perform the operations described herein for that module.Accordingly, different modules of the avatar notification system 124 mayinclude and configure different arrangements of such processors 308 or asingle arrangement of such processors 308 at different points in time.Moreover, any two or more modules of the avatar notification system 124may be combined into a single module, and the functions described hereinfor a single module may be subdivided among multiple modules.Furthermore, according to various example embodiments, modules describedherein as being implemented within a single machine, database, or devicemay be distributed across multiple machines, databases, or devices.

FIG. 4 is a flowchart depicting a method 400 of presenting a shared ARinterface at a client device 102, according to certain exampleembodiments. Operations of the method 400 may be performed by themodules described above with respect to FIG. 3. As shown in FIG. 4, themethod 400 includes one or more operations 402, 404, 406, 408, 410, and412.

At operation 402, the location module 302 accesses image data at theclient device 102, wherein the image data comprises a set of imagefeatures that define a surface of an object. For example, the image datamay be generated by a camera associated with (or communicatively coupledto) the client device 102.

In some embodiments, the image data may include a video stream generatedby the client device 102 and presented within a GUI at the client device102.

At operation 404, the location module 302 determines a position of theclient device 102. In some embodiments, the location module 302 maydetermine the position of the client device 102 based on the set ofimage features depicted in the image data presented at the client device102. For example, the set of image features may correspond to a locationor landmark within a repository (i.e., the database 120). In someembodiments, the location module 302 may determine the position of theclient device 102 based on location data accessed at the client device102.

The location data may include coordinates that indicate a geographiclocation of the client device 102, directional data indicating a headingof the client device 102, as well as translational and rotational dataindicating an orientation of the client device 102 in six degrees offreedom.

At operation 406, the presentation module 306 causes display of aprojection that extends from the position of the client device 102within a presentation of the image data at the client device 102,wherein the projection has a corresponding trajectory based on theposition of the client device 102. For example, the projection may bedisplayed as a stream of AR paint which the user of the client device102 may use to virtually paint a surrounding environment of the userpresented within the GUI of the client device 102.

In some embodiments, the projection may correspond with a graphicalproperty, such as a color or pattern, which may be associated with auser profile associated with a user of the client device 102.

At operation 408, the presentation module 306 detects an intersectionbetween the projection and a portion of the surface of the objectdepicted in the image data at the client device 102, wherein the portionof the surface of the object corresponds with attributes that include aset of surface features.

At operation 410, the presentation module 306 generates a request thatincludes an identification of the portion of the surface of the objectat the client device 102, wherein the identification of the portion mayinclude the set of surface features, as well as location data indicatinga location of the client device 102.

At operation 412, the presentation module 306 presents the portion ofthe surface of the object based on the graphical property of theprojection. As an illustrative example, the graphical property of theprojection may include a specific color or pattern. Responsive todetecting the intersection of the projection with the portion of thesurface, the presentation module 306 may display the portion based onthe specific color or pattern such that it appears as though the portionwas painted with the projection.

FIG. 5 is a flowchart depicting a method 500 of presenting a shared ARinterface, according to certain example embodiments. Operations of themethod 500 may be performed by the modules described above with respectto FIG. 3. As shown in FIG. 5, the method 500 includes one or moreoperations 502, and 504. The method 500 may be performed as a part ofthe method 400 depicted in FIG. 4, for example as a part of one or moreof the operations depicted in the method 400. In some embodiments, themethod 500 may be performed as a subroutine of operation 404 of themethod 400, wherein a position of a client device 102 is determinedbased on location data and image data.

At operation 502, the location module 304 identifies a second clientdevice 102 based on one or more factors that include the position of theuser of the client device 102 (i.e., the first client device 102). Thelocation module 304 may identity client devices within a thresholddistance of the position of the first client device 102 or may identifyall client devices located within a boundary defined by the locationmodule 304. For example, a boundary may be defined and associated with alocation. Responsive to detecting a client device (i.e., the firstclient device 102) within the boundary associated with the location, thelocation module 304 may identify a second client device 102 which isalso located within the boundary associated with the location.

In such embodiments, associating the boundary with the location mayinclude associating the boundary with one or more landmarks within thelocation, based on image features associated with the landmarks. Infurther embodiments, the boundary may include a geo-fence maintained bythe location module 304, wherein users are determined to be within theboundary of the geo-fence based on location data which may be accessedat the corresponding devices.

In some embodiments, the location module 304 may identify the clientdevices based on factors such as user profile data that includes userattributes, and user affinities. For example, responsive to detecting alocation of the first client device 102, the location module 304 mayidentify a user attribute of a user of the first client device 102, andthen identify a second client device 102 based on the location of thefirst client device 102 and the user attribute of the first clientdevice 102.

At operation 504, the user profile module 302 initiates a communicationsession between at least the first client device 102 and the secondclient device 102. In some embodiments, initiation of the communicationsession between the first client device 102 and the second client device102 may include adding the first client device 102 and the second clientdevice 102 to an existing communication session associated with thelocation, wherein the existing communication session includes aplurality of client devices which are also located in the boundaryassociated with the location.

In some embodiments, responsive to identifying the second client device102, the presentation module 306 may cause display of a notification atthe first client device 102, wherein the notification includes aninvitation to join a shared communication session with the second clientdevice 102.

In some embodiments, the communication session may include a shared ARinterface, wherein actions performed by the user of the first clientdevice 102 (i.e., painting buildings with AR content), is visible viathe shared AR interface of the communication session at the secondclient device 102.

FIG. 6 is a flowchart depicting a method 600 of presenting AR content ina shared AR interface, according to certain example embodiments.Operations of the method 600 may be performed by the modules describedabove with respect to FIG. 3. As shown in FIG. 6, the method 600includes one or more operations 602, and 604. The method 600 may beperformed as a part of the method 400 depicted in FIG. 4, for example asa part of one or more of the operations depicted in the method 400. Insome embodiments, the method 600 may be performed as a subroutine ofoperation 404 of the method 400, wherein a position of a client device102 is determined based on location data and image data.

At operation 602, the user profile module 302 assigns a graphicalproperty from among a plurality of graphical properties to a userprofile associated with the client device 102. In certain embodiments,the user profile module 302 may assign the graphical property to theuser profile associated with the client device 102 responsive todetecting the location of the client device 102. For example, responsiveto determining the location of the client device 102, the user profilemodule 302 may select a graphical property and assign the graphicalproperty to the user profile associated with the client device 102.

In some embodiments, the user profile module 302 may select thegraphical property from among the plurality of graphical propertiesbased on factors that include location attributes of the location, aswell as user attributes from the user profile associated with the clientdevice 102.

In some embodiments, the user profile module 302 may select thegraphical property from among the plurality of graphical propertiesbased on contextual data associated with the location. For example, thecontextual data may include one or more of: a number of client deviceswhich are within a boundary associated with the location; a number ofclient device which have been assigned a graphical property from amongthe plurality of graphical properties; and temporal data indicating atime in which the client device 102 entered the boundary associated withthe location.

At operation 604, the presentation module 306 generates and causesdisplay of AR content at the client device 102 based on the graphicalproperty assigned to the user profile. For example, the AR content mayinclude a display of a stream of “paint” presented at the client device,wherein the color or pattern of the paint is based on the graphicalproperty associated with the user profile. For example, as seen in theshared AR interface 805 depicted in the interface diagram 800 of FIG. 8,the AR content may include a presentation of a stream of paint, whereinthe graphical property of the stream of paint is based on the graphicalproperty assigned to the user profile.

FIG. 7 is a flowchart depicting a method 700 of presenting AR content ina shared AR interface, according to certain example embodiments.Operations of the method 700 may be performed by the modules describedabove with respect to FIG. 3. As shown in FIG. 7, the method 700includes one or more operations 702, and 704. The method 700 may beperformed as a subroutine of the method 500 depicted in FIG. 5.

At operation 702, the presentation module 306 receives location datathat identifies a location of a second client device 102, wherein thelocation data indicates a position, heading, and orientation of thesecond client device 102. For example, responsive to assigning the firstclient device 102 and the second client device 102 to a sharedcommunication session, the presentation module 306 may provide locationdata that identifies locations of the plurality of client devices partyto the shared communication session to each of the client devices in theshared communication session. In some embodiments, the presentationmodule 306 may identify one or more client devices 102 that are within athreshold distance of the first client device 102.

Software Architecture

FIG. 9 is a block diagram illustrating an example software architecture906, which may be used in conjunction with various hardwarearchitectures herein described. FIG. 9 is a non-limiting example of asoftware architecture and it will be appreciated that many otherarchitectures may be implemented to facilitate the functionalitydescribed herein. The software architecture 1006 may execute on hardwaresuch as machine 1000 of FIG. 10 that includes, among other things,processors 1004, memory 1014, and I/O components 1018. A representativehardware layer 952 is illustrated and can represent, for example, themachine 900 of FIG. 9. The representative hardware layer 952 includes aprocessing unit 954 having associated executable instructions 904.Executable instructions 904 represent the executable instructions of thesoftware architecture 906, including implementation of the methods,components and so forth described herein. The hardware layer 952 alsoincludes memory and/or storage modules memory/storage 956, which alsohave executable instructions 904. The hardware layer 952 may alsocomprise other hardware 958.

In the example architecture of FIG. 9, the software architecture 906 maybe conceptualized as a stack of layers where each layer providesparticular functionality. For example, the software architecture 906 mayinclude layers such as an operating system 902, libraries 920,applications 916 and a presentation layer 914. Operationally, theapplications 916 and/or other components within the layers may invokeapplication programming interface (API) API calls 908 through thesoftware stack and receive a response as in response to the API calls908. The layers illustrated are representative in nature and not allsoftware architectures have all layers. For example, some mobile orspecial purpose operating systems may not provide aframeworks/middleware 918, while others may provide such a layer. Othersoftware architectures may include additional or different layers.

The operating system 902 may manage hardware resources and providecommon services. The operating system 902 may include, for example, akernel 922, services 924 and drivers 926. The kernel 922 may act as anabstraction layer between the hardware and the other software layers.For example, the kernel 922 may be responsible for memory management,processor management (e.g., scheduling), component management,networking, security settings, and so on. The services 924 may provideother common services for the other software layers. The drivers 926 areresponsible for controlling or interfacing with the underlying hardware.For instance, the drivers 926 include display drivers, camera drivers,Bluetooth® drivers, flash memory drivers, serial communication drivers(e.g., Universal Serial Bus (USB) drivers), Wi-Fi® drivers, audiodrivers, power management drivers, and so forth depending on thehardware configuration.

The libraries 920 provide a common infrastructure that is used by theapplications 916 and/or other components and/or layers. The libraries920 provide functionality that allows other software components toperform tasks in an easier fashion than to interface directly with theunderlying operating system 902 functionality (e.g., kernel 922,services 924 and/or drivers 926). The libraries 920 may include systemlibraries 944 (e.g., C standard library) that may provide functions suchas memory allocation functions, string manipulation functions,mathematical functions, and the like. In addition, the libraries 920 mayinclude API libraries 946 such as media libraries (e.g., libraries tosupport presentation and manipulation of various media format such asMPREG4, H.264, MP3, AAC, AMR, JPG, PNG), graphics libraries (e.g., anOpenGL framework that may be used to render 2D and 3D in a graphiccontent on a display), database libraries (e.g., SQLite that may providevarious relational database functions), web libraries (e.g., WebKit thatmay provide web browsing functionality), and the like. The libraries 920may also include a wide variety of other libraries 948 to provide manyother APIs to the applications 916 and other softwarecomponents/modules.

The frameworks/middleware 918 (also sometimes referred to as middleware)provide a higher-level common infrastructure that may be used by theapplications 916 and/or other software components/modules. For example,the frameworks/middleware 918 may provide various graphic user interface(GUI) functions, high-level resource management, high-level locationservices, and so forth. The frameworks/middleware 918 may provide abroad spectrum of other APIs that may be utilized by the applications916 and/or other software components/modules, some of which may bespecific to a particular operating system 902 or platform.

The applications 916 include built-in applications 938 and/orthird-party applications 940. Examples of representative built-inapplications 938 may include, but are not limited to, a contactsapplication, a browser application, a book reader application, alocation application, a media application, a messaging application,and/or a game application. Third-party applications 940 may include anapplication developed using the ANDROID™ or IOS™ software developmentkit (SDK) by an entity other than the vendor of the particular platform,and may be mobile software running on a mobile operating system such asIOS™, ANDROID™, WINDOWS® Phone, or other mobile operating systems. Thethird-party applications 940 may invoke the API calls 908 provided bythe mobile operating system (such as operating system 902) to facilitatefunctionality described herein.

The applications 916 may use built in operating system functions (e.g.,kernel 922, services 924 and/or drivers 926), libraries 920, andframeworks/middleware 918 to create user interfaces to interact withusers of the system. Alternatively, or additionally, in some systemsinteractions with a user may occur through a presentation layer, such aspresentation layer 914. In these systems, the application/component“logic” can be separated from the aspects of the application/componentthat interact with a user.

“EMPHEMERAL MESSAGE” in this context refers to a message that isaccessible for a time-limited duration. An ephemeral message may be atext, an image, a video and the like. The access time for the ephemeralmessage may be set by the message sender. Alternatively, the access timemay be a default setting or a setting specified by the recipient.Regardless of the setting technique, the message is transitory.

“MACHINE-READABLE MEDIUM” in this context refers to a component, deviceor other tangible media able to store instructions and data temporarilyor permanently and may include, but is not be limited to, random-accessmemory (RAM), read-only memory (ROM), buffer memory, flash memory,optical media, magnetic media, cache memory, other types of storage(e.g., Erasable Programmable Read-Only Memory (EEPROM)) and/or anysuitable combination thereof. The term “machine-readable medium” shouldbe taken to include a single medium or multiple media (e.g., acentralized or distributed database, or associated caches and servers)able to store instructions. The term “machine-readable medium” shallalso be taken to include any medium, or combination of multiple media,that is capable of storing instructions (e.g., code) for execution by amachine, such that the instructions, when executed by one or moreprocessors of the machine, cause the machine to perform any one or moreof the methodologies described herein. Accordingly, a “machine-readablemedium” refers to a single storage apparatus or device, as well as“cloud-based” storage systems or storage networks that include multiplestorage apparatus or devices. The term “machine-readable medium”excludes signals per se.

“COMPONENT” in this context refers to a device, physical entity or logichaving boundaries defined by function or subroutine calls, branchpoints, application program interfaces (APIs), or other technologiesthat provide for the partitioning or modularization of particularprocessing or control functions. Components may be combined via theirinterfaces with other components to carry out a machine process. Acomponent may be a packaged functional hardware unit designed for usewith other components and a part of a program that usually performs aparticular function of related functions. Components may constituteeither software components (e.g., code embodied on a machine-readablemedium) or hardware components. A “hardware component” is a tangibleunit capable of performing certain operations and may be configured orarranged in a certain physical manner. In various example embodiments,one or more computer systems (e.g., a standalone computer system, aclient computer system, or a server computer system) or one or morehardware components of a computer system (e.g., a processor or a groupof processors) may be configured by software (e.g., an application orapplication portion) as a hardware component that operates to performcertain operations as described herein. A hardware component may also beimplemented mechanically, electronically, or any suitable combinationthereof. For example, a hardware component may include dedicatedcircuitry or logic that is permanently configured to perform certainoperations. A hardware component may be a special-purpose processor,such as a Field-Programmable Gate Array (FPGA) or an ApplicationSpecific Integrated Circuit (ASIC). A hardware component may alsoinclude programmable logic or circuitry that is temporarily configuredby software to perform certain operations. For example, a hardwarecomponent may include software executed by a general-purpose processoror other programmable processor. Once configured by such software,hardware components become specific machines (or specific components ofa machine) uniquely tailored to perform the configured functions and areno longer general-purpose processors. It will be appreciated that thedecision to implement a hardware component mechanically, in dedicatedand permanently configured circuitry, or in temporarily configuredcircuitry (e.g., configured by software) may be driven by cost and timeconsiderations. Accordingly, the phrase “hardware component” (or“hardware-implemented component”) should be understood to encompass atangible entity, be that an entity that is physically constructed,permanently configured (e.g., hardwired), or temporarily configured(e.g., programmed) to operate in a certain manner or to perform certainoperations described herein. Considering embodiments in which hardwarecomponents are temporarily configured (e.g., programmed), each of thehardware components need not be configured or instantiated at any oneinstance in time. For example, where a hardware component comprises ageneral-purpose processor configured by software to become aspecial-purpose processor, the general-purpose processor may beconfigured as respectively different special-purpose processors (e.g.,comprising different hardware components) at different times. Softwareaccordingly configures a particular processor or processors, forexample, to constitute a particular hardware component at one instanceof time and to constitute a different hardware component at a differentinstance of time. Hardware components can provide information to, andreceive information from, other hardware components. Accordingly, thedescribed hardware components may be regarded as being communicativelycoupled. Where multiple hardware components exist contemporaneously,communications may be achieved through signal transmission (e.g., overappropriate circuits and buses) between or among two or more of thehardware components. In embodiments in which multiple hardwarecomponents are configured or instantiated at different times,communications between such hardware components may be achieved, forexample, through the storage and retrieval of information in memorystructures to which the multiple hardware components have access. Forexample, one hardware component may perform an operation and store theoutput of that operation in a memory device to which it iscommunicatively coupled. A further hardware component may then, at alater time, access the memory device to retrieve and process the storedoutput. Hardware components may also initiate communications with inputor output devices, and can operate on a resource (e.g., a collection ofinformation). The various operations of example methods described hereinmay be performed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implementedcomponents that operate to perform one or more operations or functionsdescribed herein. As used herein, “processor-implemented component”refers to a hardware component implemented using one or more processors.Similarly, the methods described herein may be at least partiallyprocessor-implemented, with a particular processor or processors beingan example of hardware. For example, at least some of the operations ofa method may be performed by one or more processors orprocessor-implemented components. Moreover, the one or more processorsmay also operate to support performance of the relevant operations in a“cloud computing” environment or as a “software as a service” (SaaS).For example, at least some of the operations may be performed by a groupof computers (as examples of machines including processors), with theseoperations being accessible via a network (e.g., the Internet) and viaone or more appropriate interfaces (e.g., an Application ProgramInterface (API)). The performance of certain of the operations may bedistributed among the processors, not only residing within a singlemachine, but deployed across a number of machines. In some exampleembodiments, the processors or processor-implemented components may belocated in a single geographic location (e.g., within a homeenvironment, an office environment, or a server farm). In other exampleembodiments, the processors or processor-implemented components may bedistributed across a number of geographic locations.

“PROCESSOR” in this context refers to any circuit or virtual circuit (aphysical circuit emulated by logic executing on an actual processor)that manipulates data values according to control signals (e.g.,“commands”, “op codes”, “machine code”, etc.) and which producescorresponding output signals that are applied to operate a machine. Aprocessor may, for example, be a Central Processing Unit (CPU), aReduced Instruction Set Computing (RISC) processor, a ComplexInstruction Set Computing (CISC) processor, a Graphics Processing Unit(GPU), a Digital Signal Processor (DSP), an Application SpecificIntegrated Circuit (ASIC), a Radio-Frequency Integrated Circuit (RFIC)or any combination thereof. A processor may further be a multi-coreprocessor having two or more independent processors (sometimes referredto as “cores”) that may execute instructions contemporaneously.

“TIMESTAMP” in this context refers to a sequence of characters orencoded information identifying when a certain event occurred, forexample giving date and time of day, sometimes accurate to a smallfraction of a second.

“LIFT” in this context is a measure of the performance of a targetedmodel at predicting or classifying cases as having an enhanced response(with respect to a population as a whole), measured against a randomchoice targeting model.

“PHONEME ALIGNMENT” in this context, a phoneme is a unit of speech thatdifferentiates one word from another. One phoneme may consist of asequence of closure, burst, and aspiration events; or, a dipthong maytransition from a back vowel to a front vowel. A speech signal maytherefore be described not only by what phonemes it contains, but alsothe locations of the phonemes. Phoneme alignment may therefore bedescribed as a “time-alignment” of phonemes in a waveform, in order todetermine an appropriate sequence and location of each phoneme in aspeech signal.

“AUDIO-TO-VISUAL CONVERSION” in this context refers to the conversion ofaudible speech signals into visible speech, wherein the visible speechmay include a mouth shape representative of the audible speech signal.

“TIME DELAYED NEURAL NETWORK (TDNN)” in this context, a TDNN is anartificial neural network architecture whose primary purpose is to workon sequential data. An example would be converting continuous audio intoa stream of classified phoneme labels for speech recognition.

“BI-DIRECTIONAL LONG-SHORT TERM MEMORY (BLSTM)” in this context refersto a recurrent neural network (RNN) architecture that remembers valuesover arbitrary intervals. Stored values are not modified as learningproceeds. RNNs allow forward and backward connections between neurons.BLSTM are well-suited for the classification, processing, and predictionof time series, given time lags of unknown size and duration betweenevents.
